Fastener Expo Shanghai 2026 Builds a Knowledge Hub for Engineers and Buyers

In industrial manufacturing and product assembly, fasteners may look simple, but they are absolutely critical. From steel structures in construction to engine components in vehicles and precision fixing in electronics, fasteners are everywhere. As industries demand higher reliability, performance and smarter manufacturing, Fastener Expo Shanghai 2026 will take place on June 24–26, 2026 at the National Exhibition and Convention Center (Shanghai). The show will feature a special focus on fastener fundamentals, helping engineers, buyers and newcomers understand fastener types, specifications and application logic.

What Is a Fastener?

A fastener is a standardized mechanical component used to join two or more parts together. Its key feature is that it is removable and reusable, unlike welding or bonding. Fasteners are essential in automotive, aerospace, machinery, electronics and construction industries.

Main Categories of Fasteners

Threaded Fasteners

Bolts – used with nuts for high-strength connections
Screws – driven directly into materials for assembly
Nuts – internal-thread parts used with bolts

Non-threaded Fasteners

Rivets – permanent joints through plastic deformation
Pins – for positioning and shear load transfer
Clamps – for pipes and cable management

Auxiliary Parts

Washers – distribute load and prevent loosening

Key Specifications and Standards

Important parameters include diameter (M6, M8), length, pitch and strength grade (8.8, 10.9, etc.).
Main standards: ISO / GB, ANSI / ASME, DIN, JIS.

Materials and Performance

Carbon steel – cost-effective
Stainless steel – corrosion resistant
Alloy steel – high strength
Aluminum & titanium – lightweight and high performance

Typical Applications

Automotive – vibration resistance and lightweight
Construction – high load and durability
Electronics – precision and corrosion resistance
Aerospace & rail – extreme reliability and fatigue resistance
